A higher approach speed would also reduce the drift angle, but I can't believe anyone would plan a flapless landing with that in mind. The real danger is that the a/c would tend to float. There was significant headwind and therefore an additive wind correction speed increment. This extra speed should be bled off to touchdown at Vref (+gust, perhaps). With no flap drag bleeding off the speed would be extremely difficult and thus floating would be a real danger. Equally, on a wet runway, you want the a/c to squat and break through the water to avoid hydroplaning. Reduced flaps will make this difficult. You could 'plant it' to break through the water ands it bounces due lack of drag. Hm! Making a difficult job even more so.
There must be more to this than meets the eye.
